JOHN L. MOHUN', 0F NEW YORK, N. Y.

CAR ROOF.

Application filed February 21, 1920.

To all whom it may concern:

Be it known that I, JOHN L. MoHUN, a citizen' of the United States, and a resident of the city of New York, in the County of Kings and State of New York, have invented a new and useful Improvement in Car Roofs, of which the following is a specification. This invention relates principally to car roofs. of the lrigid all steel riveted type, wherein heavy gage self-supporting roof sheets extend from eaves to eaves of the car and have upstanding flanges at their side margins riveted together and covered by seam covers or outside carlines, the seam covers and the sheet flanges covered thereby being rigidly secured together from eaves to eaves. `With the above type ofroof, all of the rivets, which secure the seam flanges together, are exposed and there is a tendency for the rivets to Work loose, thus permitting water to enter the seam and cause the roof to leak. Leakage around the rivets is also sometimes caused by the workmen not driving the rivets as tight as they should be driven. The principal object of the present invention is t-.o prevent leakage around the rivets which secure the seam flanges and to obtain other advantages hereinafter appearing. The invention consists in the hereinafter described seam construction and in the arrangements and combina- -tions of parts hereinafter described and claimed.

In the accompanying drawingswherein like symbols refer to like parts wherever they occur,

Fig. 1 is a fragmentary plan view of a car roof embodying my invention, parts being broken away to more clearly illustrate the invention;

Fig. 2 is an enlarged vertical section taken crosswise of the roofon the line 2-2 in Fig. 1;

Fig. 3 is an enlarged detail cross-section taken through the side plate adjacent to a seam on the line 3--3 in Fig. 1;

Fig. 4 is a vertical cross-section through one of the seams, the section being taken longitudinally of the car at the ridge on the line 1w/lin Fig. 2;

Fig. 5 is a vertical 'cross-section throughy one of the seams, the section being taken midway between the eaves and ridge of the car on the line 5-5 of Fig. 1;

Fig. 6 is a horizontal section through one Serial No. 360,534.

of the securing bolts on the line 6-6 in Fig. 3;

Fig. 7 is a view similar to Fig. 5, sh'owing a modified form of seam, the seam flanges being shown in contact from top to bottom and the base flanges of the seam cover being shown spaced above the sheets;

In Figs. 1 to 6 of'the drawings, the roofl is shown applied to a car having metal Z-bar side plates 11, but the roof can be applied to other types of cars having wooden or metal side plates of various cross-sections. The metal roof sheetslQ are arranged crosswise of the car, extending from eaves to eaves preferablv in the form of curves or arcs, and are self-supporting. The side margins of the roof sheets are turned up forming side flanges 13. The side flanges 13 of each sheet are inclined outwardly and upwardly from the body portion thereof and the upper marginal portions of said flanges are disposed at right angles to the plane of the body of' the sheet. The sheets are placed side by side and the contacting upper marginal portions of the side flanges, except for a distance on each side of the ridge, are secured together by rivets 14. Thus, the seam flanges constitute stiffening ribs and enable the sheets to sustain such loads to which they are subjected in ordinary operation. The side seam flanges are preferably shown gradually decreasing in height from the ridge to a point near the eaves where, from thereon, their height decreases more rapidly, the flanges merging into the plane of the sheet at the eaves ends thereof. This provides the seam flanges substantially inverted U-shape section. These outside carlines are of a width Suf'- ficient to straddle the wide base portions of' the seam flanges and are provided with the lateral base flanges 17, which extend over the body portion of' the sheets on opposite sides of the seam. These outside carlines gradually decrease in height. from the ridge towards the eaves in a manner corresponding to the decreased height of the seam flanges. The eaves ends of the outside carlines are closed by abruptly decreasing their height from a point near the eaves tov their ends where they merge into th-e plane oi the lateral flanges 17 of the outside carline and are turned down in the form of the vertical end flanges 18.

A series of' equally spaced anchor and flashing members 19 are secured to the top flanges of the side plates 11 in alinement crosswise of the car, These anchor and flashing members are in the form of angle brackets whose horizontal flanges are riveted to the upper flanges of the side plates and whose vertical flanges projectdownwardly along the side of the web portions of the side plates and are riveted or otherwise secured thereto. The horizontal flanges of the bracket members are provided with upstanding vertical web portions 20 which eX- tend between the upstanding seam flanges of the roof sheets and are covered by the closed ends of the outside carlines. The outside carlines and the seam flanges are se.- cured to the web portions 20 of the anchor members by means of rivets.

At theridge, the side walls of the outside carlines are pressed inwardly towards each other as at-21 to closely embrace the seam flanges. The depressed port-ions of the outside carlines are secured to the roof sheet flanges by means of rivets 22. These rivets also form means of' securing the vertical flange of an'angle shaped running board saddle 23 to the seam covers or outside carlines. Running boards 24 are supported on the horizontal flange of the running board saddles and are secured thereto by bolts.

The depending eaves flanges 15 of the roof' sheets and the dependingveaves flanges 18 of the outside carlines are secured to the vertical web portions of the side plates by means of collar bolts 25. These collar bolts are shown and described in my Patent No. 1,069,565, dated August 5. 1913 and extend through the depending flanges of the roofl sheets and have integral collar portions 26 located between the inner surface of' the eaves anges 15 of the roof' sheets and the outer surface of the web portionof the side plates. The outer ends of' the bolts are provided with nuts 27 which clamp the eaves flanges of' the roof sheets to the collars of the bolts. The collars of the bolts are drawn tightly against the side plates by means of Massei nuts 28 threaded on the inner end of the bolts. This arrangement prevents the water from following the bolts and leaking into the car. The bolts which secure the outside carline to the side plates are located below the lower edges of the vertical flanges ot the anchor members 19 and pass through the downturned flanges 15 of the roof sheets and the downturned flanges 18 of the seam covers.

Fig. 7 illustrates a modified form of seam, In this construction, the base flanges 17a of the outside carline 16 are shown spaced above the body portion of the sheets 12. Vt'ith this arrangement the outside carline is clear of the sheets and the seam flanges 13a throughout their length, except for a distance at the ridge where the outside carline is secured to the seam flanges in the manner previousl described. This spacing of the carline a ove the sheets affords a ventilating space and prevents the accumulating of moisture, cinders and dirt in the seam, causing the sheets to rust and corrode.

In Fig. 8 the seam is shown provided with fillers'or spacers 31. These fillers are arranged between the inner walls of' the outside carline and the adjacent side faces of the seam flanges at the ridge. The `fillers are held in place by the'rivets which connect a running board saddle 32 to the carline and the carline to the roof sheet. The running board saddle is of' Tsha-ped section and its horizontal flange portions, which support the running board, extend for a distance on opposite sides of the carline to overhang the rivets and thus protect the same from the weather.

In Fig. 7, as well as in Fig. 8, the seam flanges, below the securing rivets, abut instead of being spread apart as shown in Figs. 1 to 6. This arrangement permits the securing rivets to be located closer to the plane of the sheets and prevent spreading apart of the sheets at their margins, thus better enabling the sheets to resist horizontal stresses.

Figs. 9 to 12 show my form of seam cover or outside carline in connection with different types of inside carlines. All of' these designs show means for fastening the inside carlines to the roof sheets, thus tying the roof sheets and the seam covers to the car substructure at the ridge.

1n Fig. 9 the inside carline 33 is a p-ressed steel member of U-shaped section and has lateral flanges 34 at its top for supporting the roof sheets 12. The roof sheets are secured to the side plate in the hereinbefore described manner. At the ridge, the carline 33 is provided with a short member 35 of T- section whose base flanges 36 are riveted or otherwise secured to the lateral top flanges 34 of' the carline. The web portion of' the member projects upwardly between the seam flanges 18 of the roof sheets. At this point the sides of the outside carline 13 are brought together to embrace the seam flanges 13 and, the outside carline and Ithe seam flanges, together with the running board saddle, are secured to the web portion of the 'l' member by means of rivets.

In Fig. 10, the seam is shown in connection with a carline 37 of `l"-secti0n. This carline extends from side plate to side plate and the seam flanges 13 on opposite sides of its vertical web portion are secured to said web portion by rivets. At the ridge, the outside carline 16, which covers the securing rivets, has its side walls depressed to closely embrace the seam flanges. The depressed walls of the outside carline together with the running board saddle is secured to the vertical web portion of the carline by rivets.

In Fig. 11, the seam is shown in connec tion with a built up carline comprising angle members 38. A short member 39 of T-section is secured to the top of' the angle members of the carline at the ridge. The outside carline 16 and seam flanges 13 are secured to the web portion of the ridge. member 39 of the carline 38 in the same manner as in Figs. 7 and 8. j

In Fig. 12, the seam is shown in connection witha Slightly modified form of built up carline.l This carline comprises angle members 40 whose vertical flanges are disposed back to back. At the ridge,ca plate 41 is arranged between the. vertical flanges of the angle members 40 of the carline. This plate extends upwardly between the seam flanges 13 and its upper surface terminates flush with the upper edges thereof. The seam flanges of the sheets together with the depressed side wall of the outside carline 12 are riveted or otherwise secured to the plate 41.

YVith the construction described, the roof seams, which may be of any desired type, as well as the rivets which secure the seam flanges together, are coveredby the outside carline, thus protecting the joints and the rivets from the weather and resulting in a water-tight roof. The only exposed rivets are. the rivets which connect the sheet flanges to the carlines and which also connect the running board saddle to the seam cover. These last mentioned rivets are fairly well protected by the running boards and, if desired, the saddle of Tsection, such as shown in F ig. 8, may be used to further ,protect these Irivets from the weather; The covering of the rivets which secure the seam flanges by the outside carline permits the use of cold-driven rivets.

It is noted that the roof sheets are supported at the ridge by the outside carline while at the eaves, the sheets, as well as the outside carlines, are. rigidl secured to the side plates of the car. gs shown in Figs. 9 to 12, the roof is adapted for use in connection with roofs having inside carlines and purlins with slight modification.

The. hereinbefore described arrangement is considered only as an example and as being the one most adapted to the style of roof shown.
